crypto: marvell/cesa - add support for Orion SoCs

Browse Source 
Add the Orion SoC description, and select this implementation by default
to support non-DT probing: Orion is the only platform where non-DT boards
are declaring the CESA block.

Control the allhwsupport module parameter to avoid probing the CESA IP when
the old CESA driver is enabled (unless it is explicitly requested to do
so).
